Write code to add two numbers, 5 and 7. Then display the sum on the serial monitor.

Explanation

Using the Python 3 syntax in writing the code.

First we will define a function 'add_numbers', parse in the variables x and y and return its sum as shown.

def sum_numbers (x, y):

return x+y

sum_numbers (5, 7)
